1 Wedding invitation costs can range from $1.50 each with do-it-yourself kits from craft stores to $3 or $4 each for mid-range standardized invitations on mid-weight paper to $9 or more each for invitations that use a high-end printing process -- such as engraving or letterpress -- on quality handmade or silk paper. The per-invitation cost goes up with extra folds -- tri-fold costs more than bi-fold -- or lining on the invitations or envelopes. 2  The average couple spends $659 on invitations and reply-cards, according to The Bridal Association of America.
The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050.0 mbar (105.00 kPa, 30.01 inHg), with record highs close to 1085.0 mbar (108.50 kPa, 32.04 inHg).
The average surface pressure on Venus is about 90 times that on Earth (almost as much pressure as you would experience at a depth of a kilometre in the Earthâs oceans), and the atmosphere is 96% carbon dioxide, 3.5% nitrogen, 0.015% sulphur dioxide, 0.01% water vapour and 0.007% argon.
